3-24 Customer Programming Software (CPS)
6866588D21-D Chapter 3 - MTP850 Ex/MTP810 Ex Product Information Manual March 2009
After connecting the radios CPS needs some time to detect them. Wait until all the radios are
detected and listed before clicking Continue. Otherwise the upgrading process is not performed
correctly.
When a radio cannot be detected, check if the hardware is set up properly.
After the connection is established CPS reads the radios information, lists their status and
determines whether there is an update available.
7.3 Downgrade Phone
You can decline the downgrade of some attached terminal(s) that are presented in the dialog box in
the appropriate tab(s). The header of each tab includes a check box. If a check box is unselected,
the CPS does not downgrade the radio connected to the appropriate port.
The CPS determines software type of the attached terminal via Application Image field located in
the Subscriber Unit Parameters feature of the radio codeplug. This field indicates which software -
clear or TEA1/TEA2/TEA3 encrypted - is written in the radio. The downgrade dialog box displays the
list of software versions, which the radio can be downgraded to.
CAUTION:
Do not disconnect the programming cable from the terminal during the write operation. This will
destroy your radio.
7.4 Write Software
This option is used to write (or flash) software to the phone.
CAUTION:
Do not disconnect the programming cable from the phone during the write operation. This will
destroy your terminal.
Note: The CPS will display only those fields that are applicable to the CPS programming level.
